Which is the correct equation to use as a starting point for finding the IRR of a project with these cash flows:

Year	Cash Flow
0	$	-15,400
1		7,300
2		9,100
3		5,900

a. 0 = (-15400 + 7300 + 9100 + 5900)/(1+IRR)^3

b. 0 = NPV * 7300/(1+IRR) + 9100/(1+IRR)^2 + 5900/(1+IRR)^3

c. None of the equations are helpful in finding the IRR

d. 0 =-15400 + 7300/(1+IRR) + 9100/(1+IRR)^2 + 5900/(1+IRR)^3

e. IRR =-15400 + 7300/(1+rocc) + 9100/(1+rocc)^2 + 5900/(1+rocc)^3
